I've lived in lots of places, and in rough order of getting, robbed shot and killed:

Durban, South Africa
Detroit, US
Kuwait

Then, in decreasing likelihood of getting chellenged for being in the wrong place, stabbed and seriously maimed:

Chicago, US
Croydon, UK
Dagenham, UK

But oddly enough ....... the places where you are absolutely guaranteed to get into a fight (usually fists) EVERY SINGLE NIGHT

Ripley, Derbyshire, UK
Shrewsbury, Shropshire UK

Nowhere else is as full of aggressive drunk and violent people who have no thought of consequence - possibly because they are less likely to get killed if they start.
